'Application filed April 29, 1919, Serial N o 293, 426. Renewed April 23, 1925;

To all whom it may concern." 1

' it-known thatI', CLARENCE H. BEN- NE'IT, a citizen of the United States, 1 and a resident of J amesburg, in the county" of Middlesex and State of New Jersey, have inventeda new and Iinproved Mixer, of which the following is a full, clear, and exact description. r

The :object of the-inventin is this provision of construction which shall subdivide an" explosive mixture into minute particles subsequent to its leaving the atomizer of the carburetor, together with additional means which shall even further divide the parti- "certain details along-the line 33 ofFig.

1, with part of such details of construction broken away. I r v In these variousfviews, like reference numerals designate similar parts, and the reference numeral '1 indicates a casing; open at the ends, "One of these ends is closed by' means ofahousing 2, as indiCatedatB. The housing 2 may include aring-shapedpart 4, a cap portion 5, and an air inlet, as indicated by the reference-numeral 6. I Extending' i'nwardly fromtheinner edge 30f the ring-shaped portion 4, and preferablyvintegral therewith, is a tubular member {7," vvhich is provided with an outwardly-extending-flange 8 around its upper edgeffor a purposehereinaftermore fully specified. The ring'fi'has openings, such as 9, broken through at the portion between the tube 7 and apoint intermediateto the inner face 'of'the cylindrical casing 1. Closing such openings is aring 10 forming a slidable valve, which seats against the under face of the ring 4 and is of such diameter as to completely' close the openings 9 and to be slidable along the tubular member 7 Any convenientmeans,*such as a spring 11, is interposed betweentheinnenface of the ring 10 and a shoulder, such as 12, preferably inthe apex of a yoke 20 which terminates -in tegral with thetubular member 7 tending from its outer face. 1 Extending through the casing and communicating with the atmosphere is an air tube 13'Wl110l1 projects through the tubular member 7- and terminates at a point centrally-of such tubularmember. A hollow pear-shaped casing, such as 14, is fixed to the innermost end of the tube 13; and communicating with the interior of this pearand ex shaped casing, and extending to a point in the same plane With the tube 13, is a nozzle 15 which has. connected to it a pipe 16 adapted topermit a flow of gasoline into the nozzle15, such flow being regulatedby means of ar7iy convenient valve, such as a needle valve Elhe smallerend of the pear-shaped casing 1411s open, and such opening is formed with tapered sldes, as indicated by the reference numeral 18, so as to form what might'be termed a valve seat for a valve, which includes a pointed setscrew mounted" through a base 21"ac'ting as a valve for opening 22 formed in a cap 23 serving to close the end of the tubular member 7. "A. valve stem 24:

projects" through the cap 23 and extends through the'cap portion '5 of the housing 2.: The valve-21 is normally held'seated' by means 'of an adj ustable tension provided, for instance,by' a coil spring 25 encircling the valve stem 24 and extending between the cap 5 and a nut 26 mounted upon the end of the valve stem 24: by means of screw threads whichmay be provided, such as 27 Mounted above the'annul'arflange 8, and

extending above the same, are a series of such flange by any convenient means, such as bolts'29. As illustrated in Fig. 1, these plates are heldin spaced relationshipfby any suitable means. Closing the uppermost endof thetubular member 7 is a disk 30 is a plate'34cwhichserves to close the upper ring-'shaped plates 28 which are secured to equal).

end of the casing 1. Mounted upon this plate are bolts 35, spaced ring-shaped plates 36, a disk 37, and upwardly-extending wires 38 mounted upon such disk, corresponding in every particular to the bolts 29, ringshaped plates 28, disk 30, and wires 31.

In operation it will now be seen that the fuel will enter the carburetor by means of a pipe, such as 16, and, by virtue of the suction created by the engine while running, the fuel will be atomized by means of the inrush of air through the tube 13 at a point slightly above the nozzle 15.. The mixture thus resulting would be comparatively rich and unsuitable for efficient running conditions; and I have provided, by means of the valve 21, an additional air inlet which will serve to provide a suitable mixture within the tubular member 7, it being understood that the valve 21 will open proportionately to the speed of the engine, and that the opening of such valve will proportionately open the valve, including the set screw 19, and the open end 18 of the pear-shaped member 14:. The combustible mixture will now strike the wires 31, and these wires will be vibrating to quite an extent, particularly by virtue of their upper ends being fixedly secured and their lower ends being free. After having passed the wires 31, and having its particles minutely subdivided, the combustible mixture is further broken up by passing through the closely-spaced plates 28; and, as indi cated by the arrows, the mixture will now enter the casing 1. Should the engine be running at a fairly high rate of speed, the suction created thereby will be so great that the tube 13 and the valve 21 might not be able to conduct the passage of suflicient air, which objection is overcome by the provision of the valve 10, which will permit the influx of additional air into the casing 1, which air will comingle with the combustible mixture at a point between the flange 8 and plate 30. The mixture will now pass through the plates 36 and pass the vibrating wires 38, insuring the proper mixing action of the fuel with the additional air supply by means of the valve 10, andrthe completed mixture will now pass the throttle valve 33 and into the manifold 32.

It will be noted that quite independent of the vaporization of the mixture and the introduction of additional air thereinto, that the bafiiing means comprising the two spaced plate units will affect the mixture in such a manner as to insure an intimate co-mingling of the particles thereof. Thus as in Figure .1, the mixture will flow freely through the tube 7 at a speed corresponding substantially to the speed of the fluid flow within the intake manifold (the diameter of the tube and manifold being substantially In flowing through the first baffling means the fluid mixture will have its flow retarded, incident to the fact that the casing 1 is of a far greater diameter than the tube 7. Thus although the particles of the mixture will be broken up, incident to the action of the fuel between the vibratory members and the plates 28, it will be understood that the heavier particles of the same, i. e., the drops of fuel which are not readily digested will not continue with the mixture flow, in that the same is not moving with anything like the speed of the mixture within the tube 7. Thus, although the vaporized particles of the mixture-are broken up in the passage through the first baffling means and a better explosive quality is accordingly incorporated in the mixture, the heavier drops of fuel will not continue toward the intake manifold. The mixture will now flow upwardly through the casing and in order to enter the intake manifold, it must necessarily pass around plates 36 and the wires 31 and in its passage through the second baffling means consisting of these members it is obvious that the rate of flow will be materially increased so that the particles of the mixture are so evenly distributed and minutely sub-divided sov as to form an explosive fluid in the nature of a vapor, it being obvious that a mixture of this type will be of the best possible quality for the purpose intended. v

I wish it understood that I do not'desire to be, limited to the particular arrangement illustrated, and that the construction of the various valves might readily be changed at will, and that a single set of ring-shaped plates and vibrating wires might be utilized. Also, a set of such plates and wires might be used in connection with any type of carburetor now on the market and would produce a finished mixture which would be far more eflicient in operation, as well as more economical, than the operation of the carburetor alone. i

Having now described my invention, what I desire to claim is:

1. A mixer including a casing formed with inlet and outlet openings, a series of spaced plates arranged around the inlet opening of said casing, said plates being formed with openings aligning with and forming a continuation of the inlet opening of said casing, a solid plate secured to and arranged beyond the outermost of said first named plates, and a similar series of plates arranged around said outlet opening whereby said mixture will enter through the inlet opening of said casing, pass outwardly between the first named plates beyond the edges of the same, and inwardly through the second series of plates. I

2. A mixer including a plurality of plates each formed with an opening, and arranged in spaced relationship to each other, said openings being substantially in alignment, a solid plate arranged beyond and secured to the outermost of said first named plates, and a series of vibratory members secured to said last named. plate and extending adjacent the inner edges of said first named plates. i
